Brief Summary

The purpose of Part 1 (Dose Escalation) of the study is to assess how safe and tolerable JNJ-95804306 is and to find out the most suitable dose (recommended phase 2 dose \[RP2D\]) of JNJ-95804306. The purpose of Part 2 (Dose Expansion) is to further assess the safety of JNJ-95804306 and determine the anti-tumor activity alone and/or when administered in addition to standard of care (SoC) therapy at the putative RP2D(s) regimens in participants with hematological malignancies (cancer that begins in blood-forming tissue, such as the bone marrow, or in the cells of the immune system). For US sites: The purpose of Part 1 (Dose Escalation) of the study is to assess how safe and tolerable JNJ-95804306 is and to find out the most suitable dose (recommended phase 2 dose \[RP2D\]) of JNJ-95804306.

Conditions

Hematologic Neoplasms

Outcome Measures

Primary Outcomes (2)

• Part 1: Number of Participants with Dose Limiting Toxicities (DLTs)

  A DLT is defined as any toxicity that requires discontinuation of treatment; any Grade 5 toxicity; Non-hematologic Toxicity (Grade 3 or 4); and unacceptable hematologic toxicity.

  Up to 21 days after first full dose of study drug

• Number of Participants with Adverse Events (AEs) by Severity

  An AE is any untoward medical occurrence in a participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment. Severity of AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version (v) 6.0. by using standard grades as follows: Grade 1: Mild; asymptomatic or mild symptoms; Grade 2: Moderate; minimal, local or noninvasive intervention indicated; Grade 3: Severe but not immediately life threatening; hospitalization or prolongation of hospitalization indicated; Grade 4: Life-threatening consequences; and Grade 5: Death related to AE.

  Up to 6 years 5 months

Secondary Outcomes (14)

• For US sites: Part 1: Number of Participants with Dose Limiting Toxicities (DLTs)

  Up to first 28 days after first dose of study drug

• Serum Concentrations of JNJ-95804306

  Up to approximately 6 years 5 months

• Area Under the Curve From Time of Administration until End of Dosing Interval (AUC[t]) of JNJ-95804306

  Up to approximately 6 years 5 months

• Maximum Plasma Concentration (Cmax) of JNJ-95804306

  Up to approximately 6 years 5 months

• Minimum Plasma Concentration (Cmin) of JNJ-95804306

  Up to approximately 6 years 5 months

Study Arms (2)

Arm A: R/R Acute Myeloid Leukemia (AML)/ High-Risk Myelodysplastic Syndrome (HR MDS)

EXPERIMENTAL

Participants with relapsed/refractory (R/R) AML/HR-MDS will receive JNJ-95804306 monotherapy (Arm A1) or as an addition to standard of care (SoC) therapy in AML (Arm A2) to determine the putative recommended phase 2 dose (RP2D) in Part 1 (Dose escalation) of the study. In Part 2 (Dose expansion) participants will receive JNJ-95804306 monotherapy (Arm A1) or as an addition to SoC therapy in AML (Arm A2) at the determined RP2D regimen(s). For US sites: Participants with R/R AML/HR-MDS will receive JNJ-95804306 monotherapy to determine the putative RP2D in Part 1 (Dose escalation) of the study. In Part 2 (Dose expansion) participants will receive JNJ-95804306 monotherapy at the determined RP2D regimen(s). AML SoC will not be administered for US sites.

Drug: JNJ-95804306; Drug: AML SoC

Arm B: R/R Chronic Lymphocytic Leukemia (CLL)/ Small Lymphocytic Lymphoma (SLL)

EXPERIMENTAL

Participants with R/R CLL/SLL will receive JNJ-95804306 monotherapy (Arm B1) or as an addition to SoC therapy in CLL/SLL (Arm B2 or B3) to determine the putative RP2D in Part 1 (Dose escalation) of the study. In Part 2 (Dose expansion) participants will receive JNJ-95804306 monotherapy (Arm B1) or as an addition to SoC therapy in CLL/SLL (Arm B2 or B3) at the determined RP2D regimen(s). For US sites: Participants with R/R CLL/SLL will receive JNJ-95804306 monotherapy to determine the putative RP2D in Part 1 (Dose escalation) of the study. In Part 2 (Dose expansion) participants will receive JNJ-95804306 monotherapy at the determined RP2D regimen(s). CLL/SLL SoC will not be administered for US sites.
